Review

Kiera Bonny is a frontline tank that excels against enemies that apply Unavoidable debuff. She gains [Seismic Charge] stacks on deploy, whenever she dodges 5 attacks and instantly gets max stacks when any ally is affected by Unavoidable. Her Special Skill reduces Ultimate Skill cooldown based on the number of stacks and casts, regardless of cooldown when she drops below 50% HP. 

In PVE, while Kiera’s durability is quite high, her lack of offensive utility and high cost make her an unattractive option.

In PVP, Kiera gets to perform her Deploy -> Special Skill -> Drop below 50% HP -> 2nd Special Skill -> Ultimate Skill sequence almost every deploy. She is a very potent meatball and can be worth her cost, especially if units that apply Unavoidable are relevant (e.g. Vesca, Griffin Rider Chris).

Pros & Cons
Pros

  • Very tanky meatball.

Cons

  • Ultimately is just a meatball.
